Description

Hinge mechanism with multiple preset positions

Background

Mobile computing devices have been developed to increase the functionality that becomes available to users in mobile settings. For example, a user may interact with a mobile phone, tablet computer, or other mobile computing device to check email, surf the web, compose text, interact with an application, and so forth.

Because mobile computing devices are configured to be mobile, the devices are typically designed to be used in a handheld manner. Typical ways of adapting mobile devices for other uses (e.g., placement on a table or other surface) tend to be awkward and deviate from the mobile aesthetics associated with mobile devices.

Detailed Description

Overview

Hinge mechanisms having multiple preset positions are described. In at least some implementations, the hinge mechanism allows the support component to be adjustably attached to an apparatus, such as a computing device. For example, a hinge mechanism may be used to rotatably attach a stand to a mobile computing device. The kickstand is rotatable via a hinge mechanism to various positions to provide support for different orientations of the computing device. For example, a stand may be positioned to hold a computing device in a typing orientation such that input may be provided via an associated input device. As another example, the stand may be positioned to allow viewing and/or interaction with the computing device, such as in a portrait viewing orientation.

In at least some embodiments, the hinge mechanism utilizes preset hinge positions that enable the stand to be placed in different preset positions. Further, the hinge mechanism includes a rotation center outside the hinge mechanism. Thus, the stand may conform to the contour of the computing device when in the closed position and maintain a minimum outer contour when moving between different preset positions. According to implementations, the hinge mechanism includes an emergency escape position that enables the stand to rotate past a normal operating position without damaging the stand or disengaging the stand from an associated device.

In at least some implementations, the hinge mechanisms discussed herein are configured such that the attached support component tends to "snap" into various preset positions. Generally, snapping refers to movement of a hinge mechanism in response to a force generated within the hinge mechanism, such as by a hinge spring and/or other component providing a spring force to the hinge mechanism. In at least some implementations, the engagement occurs when the user releases the support assembly, e.g., independently of a force applied by the user to the support assembly. For example, the torque force applied during movement of the hinge mechanism is such that the hinge mechanism is not normally seated in a position other than the preset position unless held there by the user. Thus, the torque forces at work during movement of the attached support component provide a form of tactile feedback indicating to the user whether the support component is positioned in the normal operating position (e.g., at the preset position of the hinge mechanism). Various attributes and components of an example hinge mechanism are presented in detail below.

In the following discussion, an example environment is first described in which the techniques described herein may be employed. The embodiments discussed herein are not limited to the example environment, and the example environment is not limited to the embodiments discussed herein. Next, example device orientations in accordance with one or more embodiments are discussed. Next, an example stent in accordance with one or more embodiments is described. Next, example hinges for bracket attachment in accordance with one or more embodiments are discussed. Next, a section entitled "Hinge Responsiveness Profile" discusses an example moment Profile for Hinge movement in accordance with one or more embodiments. Finally, example systems and devices that can implement the techniques described herein are discussed.

Example Environment

FIG. 1 is an illustration of an environment 100 in an example implementation that is operable to employ techniques described herein. The illustrated environment 100 includes an example of a computing device 102 physically and communicatively coupled with an input device 104 via a flexible hinge 106. The computing device 102 may be configured in a variety of ways. For example, the computing device 102 may be configured for mobile use, such as a mobile phone, illustrated tablet computer, wearable device, and so forth.

Although the embodiments presented herein are discussed in the context of a tablet device, it will be appreciated that various other types and form factors of devices may be utilized in accordance with the claimed embodiments. Thus, the computing device 102 may range from a full resource device with substantial memory and processor resources to a low resource device with limited memory and/or processing resources. An example implementation of computing device 102 is discussed below with reference to fig. 36.

Computing device 102 is illustrated as including input/output module 108, input/output module 108 representing functionality related to processing input of computing device 102 and rendering output of computing device 102. Input/output module 108 may handle various different inputs, such as inputs relating to functions of keys corresponding to input device 104, keys of a virtual keyboard displayed by display device 110 to identify a touch gesture and cause an operation corresponding to the touch gesture to be performed, the touch gesture being recognizable through touch screen functionality of input device 104 and/or display device 110. Thus, the input/output module 108 may support a variety of different input technologies by recognizing and utilizing divisions between types of input including key presses, touch gestures, touchless gestures recognized via camera functionality of the computing device 102, and the like. In the illustrated example, the input device 104 is configured with an input portion that includes a keyboard and a trackpad having a QWERTY key arrangement, although other key arrangements are also contemplated. In addition, other non-conventional configurations are also contemplated, such as game controllers, configurations that mimic musical instruments, and so forth. Thus, the input device 104 and the keys included with the input device 104 may be configured in a variety of different configurations to support a variety of different functions.

As previously described, in this example, the input device 104 is physically and communicatively coupled to the computing device 102 through the use of the flexible hinge 106. The flexible hinge 106 is flexible in that the rotational movement supported by the hinge is achieved by flexing (e.g., bending) of the material forming the hinge, as opposed to mechanical rotation as supported by a pin (although this embodiment is also contemplated). Further, the flexible rotation can be configured to support movement in one or more directions (e.g., vertically in the figure) while limiting movement in other directions, such as lateral movement of the input device 104 relative to the computing device 102. This may be used to support consistent alignment of the input device 104 relative to the computing device 102, such as to align sensors for changing power states, application states, and so forth.

Example device orientation

According to embodiments, a variety of different orientations of the computing device 102 are supported. For example, the rotational movement may be supported by the bendable hinge 106 such that the input device 104 may abut the display device 110 of the computing device 102 and thereby act as a cover, as shown in the example orientation 200 of fig. 2. Thus, the input device 104 may be used to protect the display device 110 of the computing device 102 from damage.

As shown in the example orientation 300 of fig. 3, a typing schedule may be supported. In this orientation, the input device 104 lies flat against a surface, and the computing device 102 is disposed at an angle that permits viewing of the display device 110, such as, for example, by using a stand 302 disposed on a rear surface of the computing device 102.

Naturally, various other orientations are supported in addition to those explicitly illustrated and discussed herein.

Support frame

The described stand can be used as a support assembly that enables a variety of different orientations of the computing device 102. For example, consider the following implementations of a stent according to embodiments.

Fig. 4 illustrates an orientation 400 and includes the stent 302 in a closed position. In the closed position, the stand 302 forms a portion of the rear surface 402 of the computing device 102 such that the stand 302 conforms to the surface contour of the computing device 102. For example, when the stand 302 is in the closed position, the stand 302 is integrated into the computing device 102 and protrudes from the plane formed by the back surface 402.

Fig. 5 illustrates that the stand 302 may be rotated away from the back surface 402 of the computing device 102 to a position 500. For example, the stand 302 may be rotationally attached to the computing device 102 along the slot 502 via a hinge mechanism. Examples of such hinge mechanisms are detailed below.

In at least some implementations, the position 500 corresponds to a preset position of the cradle 302.

For example, the cradle 302 may snap into position 500 when a user applies pressure to the cradle 302 away from the rear surface 402.

As described in detail below, the hinge mechanism employed to attach the kickstand 302 to the computing device 102 may utilize spring pressure and stop settings to provide preset open positions for the kickstand 302. In this example, the location 500 is associated with an angle 504 between a rear surface of the computing device 102 and the stand 302. For example, angle 504 may range from 45 degrees (45 °) to 55 degrees (55 °). The angle 504 is, for example, approximately 48, +/-3. However, any suitable angle and/or range of angles may be employed.

According to implementations, the position 500 places the front surface of the display device 110 at an angle 506 relative to a vertical line 508. Vertical line 508 is, for example, normal (i.e., 90 °) to a surface 510 on which computing device 102 and stand 302 are placed. In this particular example, the angle 506 is approximately 24, +/-3. Angle 506 is, for example, half of angle 504.

As illustrated, the input device 104 may be rotated away from the computing device 102 and supported by the stand 302. The location 500 may, for example, enable the display device 110 to be viewed and enable input to be provided to the computing device 102 via the input device 104. Alternatively or additionally, the location 500 enables the user to interact with a touch screen of the computing device 102.

Fig. 6 illustrates that the stand 302 may be rotated away from the back surface 402 of the computing device 102 to a position 600. For example, the stand 302 may be further rotated through position 500 to position 600.

In at least some implementations, the position 600 corresponds to other preset positions of the bracket 302. For example, the cradle 302 may snap into position 600 when a user applies pressure to the cradle 302 away from the rear surface 402 (e.g., past position 500). In this example, the location 600 is associated with an angle 602 between a rear surface of the computing device 102 and the stand 302. For example, the angle 602 may range from 80 degrees (80 °) to 85 degrees (90 °). The angle 602 is, for example, approximately 84, +/-4. However, any suitable angle and/or range of angles may be employed. Further, the slot 502 may be maintained (e.g., slot width) during rotation to the position 600.

With the stand 302 in position 600, the computing device 102 supports a variety of different usage scenarios. For example, consider the following two example scenarios.

Fig. 7a illustrates a side view of the computing device 102 in an orientation 700 and with the stand 302 positioned in position 600. In contrast to the orientation discussed previously (such as orientation 300 discussed above with reference to fig. 3), at location 700, the computing device is tilted. As illustrated, the orientation 700 presents the display device 100 at a more open angle that supports different usage scenarios. For example, the orientation 700 supports use of the computing device 102 in a user's knee (such as during air travel). Various other usage scenarios are supported by the orientation 700, such as for tall users who may have a higher viewing angle, use on low surfaces (e.g., coffee tables), and so on.

According to implementations, the orientation 700 positions the front surface of the display device 110 at an angle 702 relative to a vertical line 704. The vertical line 704 is, for example, normal (i.e., 90 °) to a surface 706 on which the computing device 102 and the stand 302 are placed. In this particular example, the angle 702 is approximately 42, +/-5. Angle 702 is, for example, half of angle 602.

When the stand 302 is in the position 600, the computing device 102 may also be rotated sideways (e.g., into a portrait viewing position) and supported via the stand 302. For example, consider the orientation 708 illustrated in fig. 7 b.

Fig. 7b illustrates a rear view of computing device 102 in orientation 708, where computing device 102 is shown rotated into a portrait viewing position, such as 90 degrees (90 °) from the orientation illustrated in fig. 1. Further, the stand 302 is positioned at the location 600 such that the computing device 102 reclines rearward and is supported by the stand 302 on the surface 710. According to implementations, placing the computing device 102 in the orientation 708 can cause the viewing orientation of the display device 110 to be rotated into a portrait view.

In fig. 7b, the computing device 102 is illustrated without the input device 104. Thus, in at least some embodiments, the input device 104 can be separate from the computing device 102 such that the computing device 102 has functionality that is independent of the input device 104. For example, the bendable hinge 106 may use a magnetic attachment mechanism that holds the input device 104 to the computing device 102 via magnetic force. Thus, a user may hold the computing device 102 and the input device 104 and may pull the two apart by overcoming the magnetic attraction between them.

When separate from the input device 104, the computing device 102 may provide various functions. For example, a user may view content, such as movies and/or streaming media content, via the computing device 102. Further, the user may interact with the touch screen functionality of the display device.

Accordingly, placing the stand 302 at the location 600 may enable a user to place a computing device in a landscape and/or portrait orientation, and view and/or interact with the computing device in such an orientation.

Fig. 8 illustrates that the stand 302 can be rotated away from the back surface 402 of the computing device 102 to a position 800. For example, the stand 302 may be rotated further past position 600 to position 800.

In at least some implementations, the position 800 corresponds to other preset positions of the stent 302. For example, the cradle 302 may snap into position 800 when a user applies pressure to the cradle 302 away from the rear surface 402 (e.g., past position 600). In this example, the location 800 is associated with an angle 802 between a rear surface of the computing device 102 and the stand 302. For example, the angle 802 may range from 113 degrees (113 °) to 123 degrees (123 °). The angle 602 is, for example, approximately 118, +/-5. However, any suitable angle and/or range of angles may be employed.

According to implementations, the position 800 places the front surface of the display device 110 at an angle 804 relative to a vertical line 806. The vertical line 806 is, for example, normal (i.e., 90 °) to a surface 808 on which the computing device 102 and the stand 302 are placed. In this particular example, the angle 804 is approximately 59, +/-5. Angle 804 is, for example, half of angle 802.

Fig. 9 illustrates a view of an inner surface 900 of the scaffold 302 in accordance with one or more embodiments. In this example, the stand 302 is illustrated in the context of an outline of a chassis of the computing device 102. The interior surface 900 includes hinge mounts 902a, 902b that serve as mounting points for hinge mechanisms used to attach the stand 302 to the computing device 102. Examples of hinge mechanisms are discussed below.

Hinge for component attachment

According to various embodiments, a variety of different hinge mechanisms may be used to attach various components. Some example hinge mechanisms and hinge arrangements are discussed below.

Fig. 10 illustrates an exploded rear view 1000 of the chassis and stand 302 of the computing device 102. Included in the rear view 1000 are hinges 1002a and 1002b that may be used to attach the stand 302 to the computing device 102. The hinges 1002a, 1002b are configured to be installed internally in the computing device 102, such as via suitable attachment methods and/or devices.

As discussed above with reference to fig. 9, the bracket 302 may be attached to the pivoting portions of the hinges 1002a, 1002b via hinge mounts 902a, 902 b. Thus, attachment to the hinges 1002a, 1002b enables the stand 302 to pivot between various positions relative to the computing device 102.

Fig. 11 illustrates components of an example hinge 1100 in accordance with one or more embodiments. For example, the hinge 1100 may represent an implementation of the hinges 1002a, 1002b discussed above. However, this is not intended to be limiting, and hinge 1100 may be used as a hinge mechanism for a variety of different components and in a variety of different attachment scenarios. Hinge 1100 and its various components may be formed using any suitable material and/or combination of materials, such as metals, plastics, polymers, alloys, and so forth.

The components of the hinge 1100 include a hinge frame 1102 in which various other components of the hinge 1100 can be placed. For example, the hinge frame 1102 can be mounted to and/or within a device (e.g., the computing device 102) and serve as a support structure for other components of the hinge 1100.

Further comprising a cam 1104, a cam follower 1106, a support plate 1108a and a support plate 1108 b. As detailed elsewhere herein, the interaction between the cam 1104 and the cam follower 1106 within the hinge 1100 provides a particular responsiveness profile during manipulation of a component (e.g., the bracket 302) attached to the hinge 110 by a user. In addition, the support plates 1108a, 1108b provide lateral support to the hinge 1100 in each open position and enable the hinge 110 to be positioned in each open position. For purposes of discussion herein, support plates 1108a, 1108b may be referred to as support plates 1108.

The hinge 1100 also includes a hinge spring 1110, the hinge spring 1100 applying pressure to the cam follower 1106 when the components are placed in their respective positions within the hinge frame 1101. Additional details regarding the components and function of the hinge 1100 are now discussed.

Fig. 12 illustrates details of portions of the hinge frame 1102. The view of the hinge bracket 1102 presented in fig. 12 is rotated 108 degrees relative to the view illustrated in fig. 11. The hinge frame 1102 includes hinge mounts 1200a and 1200b, and the hinge frame 1102 and thus the hinge 1100 can be mounted to a device through the hinge mounts 1200a and 1200 b. For example, the hinge mounts 1200a, 1200b represent apertures through which a securing mechanism, such as a screw or bolt, may be positioned and secured into an apparatus, such as the computing device 102.

The hinge frame 1102 further includes a cam follower mounting portion 1202 into which a cam follower 1106 may be mounted. Although not explicitly illustrated herein, the cam follower mounting portion 1202 includes similar portions on opposing inner surfaces of the hinge frame 1102, thereby forming a bracket into which the mounting portion of the cam follower 1106 may be attached.

The plate guides 1204a, 1204b represent raised portions on the inner surface of the hinge frame 1102 that are used to mount the support plates 1108a, 1108b in the hinge frame 1102. For example, the plate guides 1204a, 1204b represent raised portions (e.g., curved tracks) on opposite inner surfaces of the hinge frame 1102 that are mirror images of each other. Generally speaking, the support plates 1108a, 1108b engage the plate rails 1204a, 1204b to retain the support plates 1108a, 1108b within the hinge frame 1102. The plate guides 1204a, 1204b cause rotational movement of the support plates 1108a, 1108b during movement of the components attached to the hinge 1100 between one or more open positions. As further illustrated herein, rotational movement of the support plates 1108a, 1108b enables the attached components to be positioned in various different positions.

The hinge frame 1102 further includes a spring mount 1206, the spring mount 1206 representing a surface on which the hinge spring 1110 is placed. As described in further detail elsewhere herein, placing the hinge spring 1110 on the spring mount 1206 enables the hinge spring 1110 to exert pressure on the cam follower 1106. The spring pressure on the cam follower 1106 holds the cam follower on the cam 1104 and thereby enables the cam 1104 to be held in various preset positions.

Fig. 13 illustrates details of portions of the support plates 1108a, 1108 b. Illustrated as part of the inner support surface 1300 of the support plate 1108a is a cam rail 1302. Although not illustrated herein, the support plate 1108b similarly includes a corresponding cam rail 1302 on its inner surface. Generally, the cam rails 1302 protrude from each surface of the respective support plate 1108a, 1108b and engage the cam 1104 such that the cam 1104 is movably attached to the hinge 1100. The cam track 1302 enables rotational movement of the cam 1104 relative to the hinge frame 1102 during movement of the components attached to the cam 1104. As further illustrated herein, rotational movement of the cam 1104 enables the attached components to be placed in various positions.

The outer surface 1304 of the support plate 1108b includes a support channel 1306 that engages the plate rail 1204b of the hinge bracket 1102 introduced above. For example, the support channel 1306 is sized such that the plate guide 1204b fits within the support channel 1306 when the support plate 1108 is installed within the hinge frame 1102. During movement of the support plate 1108b relative to the hinge frame 1102, the support channel 1306 slides relative to the plate track 1204b to enable rotational movement of the support plate 1108b relative to the hinge frame 1102. Although not illustrated above, the outer surface of the support plate 1108a similarly includes a respective plate channel 1306 that engages the plate track 1204a of the hinge frame 1102. Further details of the support plate 1108 are discussed below.

Fig. 14 illustrates example details of the cam 1104. The cam 1104 includes an inner cam surface 1400 and outer cam surfaces 1402a, 1402 b. As illustrated, the inner cam surface 1400 is recessed in the channel along an inner portion of the cam 1104. The inner cam surface 1400 is located, for example, along the longitudinal axis of the center of the cam 1104.

The outer cam surfaces 1402a, 1402b are positioned on either side of the inner cam surface 1400 and project above the inner cam surface 1400. According to implementations, the outer cam surfaces 1402a, 1402b are mirror images of each other and may be referred to herein as outer cam surfaces 1402. As described in further detail below, the inner and outer cam surfaces 1400, 1402a, 1402b have specific surface profiles that engage the cam follower 1106 to provide a specific response profile during movement of the attached assembly.

The cam 1104 further includes a cam channel 1404 and an assembly mounting portion 1406. The cam channel 1404 is formed such that when the cam 1104 is mounted in the hinge frame 1102 relative to the support plate 1108, the cam channel 1404 engages the cam track 1302 of the support plate 1108. Although not illustrated herein, the opposite side of the cam 1104 includes a respective cam channel 1404. The dimensions of the cam rail 1302 of the support plate 1108 are such that the cam rail 1302 fits within the cam channel 1404, for example. During movement of the cam 1104 relative to the hinge frame 1102, the cam channel 1404 slides relative to the cam rail 1302 to enable rotational movement of the cam 1104 relative to the support plates 1108a, 1108 b.

Component mounting surface 1406 represents a portion of cam 1104 that may be used to mount a component (e.g., bracket 302). For example, the component mounting surface 1406 includes a surface property that engages and/or interlocks with a component to stabilize the component relative to the cam 1104. Alternatively or additionally, the component mounting surface 1406 may include one or more apertures that may be used to place a securing device, such as a screw or bolt, to secure the hinge to the component.

Fig. 15 illustrates details of the top surface 1500 of the cam follower 1106. The top surface 1500 includes a follower pivot 1502 formed to engage within a cam follower mount 1202 (introduced above) of the hinge frame 1102. For example, the follower pivot 1502 is shaped such that it slidably rotates within the cam follower mount 1202 during movement of the various components of the hinge 1100.

The top surface 1500 of the cam follower 1106 further includes a spring platform 1504 configured to engage the hinge spring 1110. For example, spring tension from the hinge spring 1110 relative to the spring platform 1504 holds the cam follower 1106 to the cam 1104. Thus, the spring tension relative to the cam follower 1106 results in a reaction at the cam 1104 that provides a torque response at the cam 1104. As discussed herein, this moment response is caused, at least in part, by the interaction between the shapes of the cam 1104 and the cam follower 1106 and their respective surfaces.

For example, depending on the angular position and direction of motion of the cam 1104, the movement of the cam 1104 may be either resisted (e.g., opposed) or driven. The interaction between the different elements of hinge 1100 provides a "crisp" response of the attached component (e.g., bracket 302).

Fig. 16 illustrates details of the bottom surface 1600 of the cam follower 1106. The bottom surface 1600 includes the lower portion of the follower pivot 1502 and the spring platform 1504 introduced above.

The bottom surface 1600 further includes an inner follower surface 1602 and outer follower surfaces 1604a, 1604 b. For purposes of discussion, the outer follower surfaces 1604a, 1604b may be referred to as outer follower surfaces 1604. The inner follower surface 1602 protrudes from the bottom surface 1600 relative to the outer follower surfaces 1604a, 1604 b. As detailed elsewhere herein, the inner follower surface 1602 and the outer follower surfaces 1604a, 1604b interact with the respective surfaces of the cam 1104 to provide a particular moment response of the components attached to the hinge 1100.

Fig. 17 illustrates the location of various vertical cross-sections of the hinge 1100, which will be used in subsequent figures to describe the function and properties of the hinge 1100. Including a first cross-section 1700, a second cross-section 1702, and a third cross-section 1704. In general, these cross-sections define respective planes through the hinge 1100. Reference will be made to these different cross-sections in the subsequent discussion. Further illustrated are the hinge frame 1102, the cam 1104, the support plates 1108a, 1108b, and the bottom portion of the spring platform 1504 of the cam follower 1106.

Fig. 18 illustrates the computing device 102 with the stand 302 in position 1800. In at least some embodiments, the position 1800 corresponds to a closed position of the stent 302, such as discussed above with reference to fig. 4. Further illustrated is a partial side cutaway view 1802 of the computing device 102, the computing device 102 including the stand 302 attached to the cam 1104 of the hinge 1100 in a closed position. The cross-sectional view 1802 corresponds, for example, to the section 1704 illustrated above. In partial side view 1802 and subsequent views presented in subsequent figures, hinge 1100 is illustrated with stand 302 and portions of a rear surface of computing device 102, but without other portions of computing device 102.

In cross-section 1802, the cam 1104 is cut longitudinally down the center, and thus the illustrated cross-section of the cam 1104 illustrates the surface profile of the inner cam surface 1400 introduced above. The cam follower 1106 is also split longitudinally down the center, and thus the illustrated cross-section of the cam follower 1106 illustrates the surface profile of the inner follower surface 1602.

At position 1800, the force exerted by the hinge spring 1110 holds the cam follower 1106 against the cam 1104. In addition, the interaction between the cam follower 1106 and the cam 1104 causes the movement of the bracket 302 to be resisted. For example, the inner follower surface 1602 presses against the inner cam contact 1804 and the hinge spring 1110 resists rotational movement of the cam follower 1106 on the follower pivot 1502. Thus, pressure from the cam follower 1106 against the cam 1104 holds the kickstand 302 in the closed position on the computing device 102 in the absence of a force applied by the user to the kickstand 302.

Fig. 19 illustrates the computing device 102 introduced above with the stand 302 in position 1800. Further illustrated is a partial side cutaway view 1902 of the computing device 102, the computing device 102 including the stand 302 attached to the cam 1104 of the hinge 1100 in a closed position. The cross-sectional view 1902, for example, corresponds to the cross-section 1702 illustrated above.

Illustrated as part of the cross-sectional view 1902 are the outer follower surface 1604 of the cam follower 1106 and the outer cam surface 1402 of the cam 1104. As illustrated, in position 1800 (e.g., the closed position), the outer follower surface 1604 does not contact the outer cam surface 1402.

Fig. 20 illustrates the stent 302 in position 2000. In at least some embodiments, position 2000 corresponds to a first preset open position of cradle 302, such as position 500 illustrated with reference to fig. 5. Further illustrated is a partial side cutaway view 2002 of the computing device 102, the computing device 102 including the stand 302 attached to the cam 1104 of the hinge 1100 in a first open position. The cross-sectional view 2002, for example, corresponds to the cross-section 1704 illustrated in fig. 17.

According to implementations, movement of brace 302 from position 1800 to position 2000 is initially resisted by pressure from inner follower surface 1602 against inner cam contact 1804. However, as movement of inner cam contact 1804 travels past inner follower point 2004, pressure from inner follower surface 1602 against inner cam contact 1804 drives cam 1104 into position 2000. For example, if a user opens the cradle 302 starting at position 1800, but releases the cradle 302 before the inner cam contact 1804 travels past the inner follower point 2004, the cam 1104, and thus the cradle 302, will snap back into the closed position (e.g., position 1800).

However, if the user manipulates the brace 302 such that the inner cam contact 1804 travels past the inner follower point 2004, pressure from the cam follower 1106 against the cam 1104 drives the cam 1104 into the position 2000 (e.g., the first open position). For example, if the user releases the bracket 302 after the inner cam contact 1804 travels past the inner follower point 2004, the cam 1104 (and thus the bracket 302) will snap into position 2000.

According to implementations, the hinge 1100 has a center of rotation 2006 that is external to the hinge itself. For example, the center of rotation 2006 is substantially coincident with the seam 502 between the stand 302 and the stationary portion of the back surface 402 of the computing device 102. Moreover, in at least some implementations, the center of rotation 2006 is consistent (e.g., does not change) as the hinge 1100 is repositioned among the preset open positions discussed herein. This enables the stent 302 to maintain a consistent rotational profile and the width of the slots 502 to remain substantially consistent (e.g., within +/-0.050 millimeters) during rotation of the stent 302 among the different preset positions discussed herein.

Fig. 21 illustrates the computing device 102 introduced above with the stand 302 in position 2000. Further illustrated is a partial side sectional view 2100 of the computing device 102, the computing device 102 including the bracket 302 attached to the cam 1104 of the hinge 1100 in an open position. The cutaway view 2100 corresponds, for example, to the section 1702 illustrated above. According to implementations, cutaway view 2002 (above) and sectional view 2100 illustrate different sections of the same location (e.g., location 2000) of hinge 1100.

The outer cam surface 1402 of the cam 1104 and the outer follower surface 1604 of the cam follower 1106 are illustrated in cutaway 2100. Further illustrated is a first cam catch 2102 on the outer cam surface 1402 that engages a first follower catch 2104 on the outer follower surface 1604. Generally, the first cam catch 2102 and the first follower catch 2104 represent surface features on the outer cam surface 1402 and the outer follower surface 1604, respectively.

According to implementations, the engagement of the first cam catch 2102 with the first follower catch 21004 enables the cradle 302 to be permanently retained in position 2000. For example, spring pressure from the hinge spring 1110 holds the first cam catch 2102 against the first follower catch 2104. In at least some implementations, the first cam catch 2102 will not disengage the first follower catch 2104 in the absence of an external force applied directly and/or indirectly to the cradle 302.

For example, the hinge 1100 is configured such that the hinge 1100 will not disengage the position 2000 unless a specified threshold force is applied to the bracket 302. In at least some implementations, exceeding a threshold closing force relative to the stent 302 in one direction closes the stent, and exceeding a threshold opening force relative to the stent 302 in another direction opens the stent 302 further past the position 2000.

According to one or more implementations, contact between the cam 1104 and the cam follower 1106 occurs between the inner cam surface 1400 and the inner follower surface 1602 when the hinge 1100 is in a position from the closed position 1800 through to the open position 2000. For example, for a range of carriage angles from 0 degrees (e.g., position 1800) up to position 2000, the outer cam surface 1402 does not contact the outer follower surface 1604.

However, starting from position 2000 and continuing to further open positions (such as those discussed below), contact between the cam 1104 and the cam follower 1106 transitions to the outer cam surface 1402 and the outer follower surface 1604. In these further open positions, for example, the inner cam surface 1400 is positioned away from the inner follower surface 1602 and does not contact the inner follower surface 1602. Thus, as detailed herein, the responsiveness of the hinge 1100 between at least some positions varies based on the surface profiles of the different cam and cam follower surfaces and also based on which surfaces engage at a particular position.

Although the discussion herein is presented with reference to a particular outer follower surface 1604 and a particular outer cam surface 1402, it will be appreciated that similar features and interactions apply to other outer follower surfaces and outer cam surfaces, depending on the implementation.

Fig. 22 illustrates a partial rear view 2200 of the computing device 102 with the kickstand 302 in position 2000. The rear view 2200 illustrates that in at least some implementations, when the carriage is moved to the position 2000, the support plates 1108a, 1108b remain recessed within the hinge frame 1102 and the cam 1104 rotates out of the hinge frame 1102. However, this is not intended to be limiting, and the support plate 1108 may move in response to movement of the cam 1104, for example, due to contact between the cam rail 1302 and the cam channel 1404.

Fig. 23 illustrates cradle 302 in position 2300. In at least some embodiments, the position 2300 corresponds to a second preset open position of the stand 302, such as the position 600 illustrated with reference to fig. 6. The cradle 302 is placed in position 2300, for example, in response to the user opening the cradle 302 further past the above-introduced position 2000. Further illustrated is a partial side sectional view 2302 of the computing device 102, the computing device 102 including the stand 302 attached to the cam 1104 of the hinge 1100 in a first open position. The cross-sectional view 2302, for example, corresponds to the cross-section 1702 illustrated above.

According to implementations, movement of the cradle 302 from position 2000 to position 2300 is initially resisted by pressure from the first follower fastener 2104 against the first cam fastener 2102. However, as the movement of the first cam catch 2102 travels past the outer follower point 2304, pressure from the outer follower surface 1604 against the first cam catch 2102 drives the cam 1104 into position 2300. In position 2300, the first cam catch 2102 engages with the second follower catch 2306.

For example, if the user begins to open the cradle 302 further past position 2000, but releases the cradle 302 before the first cam catch 2102 travels past the outer follower point 2304, the cam 1104, and thus the cradle 302, will snap back into the closed position 2000. However, when movement of the cradle 302 travels past position 2000 such that the first cam catch 2102 travels past the outer follower point 2304, the cam 1104, and thus the cradle 302, will snap into position 2300. For example, consider a user releasing the bracket 302 when a first cam catch is between the outer follower point 2304 and a second follower catch 2306. In such a case, the sloped profile of the outer follower surface 1604 is such that pressure from the outer cam follower 1604 (provided by the hinge spring 1110) drives the cam 1104, and thus the stand 302, into the position 2300 independently of an externally applied (e.g., user applied) force.

According to implementations, engagement of the first cam catch 2102 with the second follower catch 2306 enables the cradle 302 to remain in position 2300. For example, the spring pressure from the hinge spring 1110 holds the second follower catch 2306 on the first cam catch 2101 and thereby prevents the cam 1104, and thus the bracket 302, from disengaging the position 2300 unless sufficient external force is applied. Thus, in the absence of a force applied directly and/or indirectly to the carriage 302, the first cam catch 2102 will not disengage the second follower catch 2306.

For example, hinge 1100 is configured such that hinge 1100 will not disengage position 2300 unless a specified threshold force is applied to brace 302. In at least some implementations, exceeding a threshold closing force relative to the scaffold 302 transitions the scaffold back to position 2000 and exceeding a threshold opening force relative to the scaffold 302 opens the scaffold 302 further past position 2300.

Note that in position 2300, the second cam catch 2308 engages the cam stop 2310 of the support plate 1108. As described in further detail below, the engagement of the second cam catch 2308 with the cam stop 2310 allows movement of the support plate 1108 to support a further open position of the bracket 302.

Fig. 24 illustrates the stent 302 in the above introduced position 2300. Further illustrated is a partial side cutaway view 2400 of the computing device 102, the computing device 102 including the bracket 302 attached to the cam 1104 of the hinge 1100 in a second open position. The cutaway view 2400 corresponds to, for example, the cross-section 1704 illustrated in fig. 17.

The cutaway view 2400 shows that when the bracket 302 is in position 2300, the inner cam surface 1400 is not in contact with the inner follower surface 1602. As described above, contact between the cam 1104 and the cam follower 1106 in each open position after the open position 2000 occurs between the outer cam surface 1402 and the outer follower surface 1604 (illustrated in other figures), and not between the inner cam surface 1400 and the inner follower surface 1602.

Fig. 25 illustrates a partial back view 2500 of the computing device 102 with the stand 302 in position 2300. The cam 1104 and support plates 1108a, 1108b are further illustrated.

Fig. 26 illustrates the stent 302 in position 2600. In at least some embodiments, position 2600 corresponds to a third preset open position of stand 302, such as position 800 illustrated with reference to fig. 8. For example, in response to the user opening stent 302 further past the above-introduced position 2300, stent 302 is placed in position 2600. Further illustrated is a partial side cutaway view 2602 of the computing device 102, the computing device 102 including the bracket 302 attached to the cam 1104 of the hinge 1100 in a third open position. The cutaway view 2602 corresponds, for example, to the section 1702 illustrated in fig. 17.

According to implementations, movement of the carriage 302 from position 2300 to position 2600 is initially resisted by pressure from the second follower catch 2306 relative to the first cam catch 2102. However, as the movement of the first cam catch 2102 travels past the outer follower point 2604, pressure from the outer follower surface 1604 against the first cam catch 2102 drives the cam 1104 into position 2600. In position 2600, the first cam catch 2102 engages the outer follower surface 1604.

For example, if a user begins to open the cradle 302 further past the position 2300, but releases the cradle 302 before the first cam catch 2102 travels past the outer follower point 2604, the cam 1104, and thus the cradle 302, will snap back into the closed position 2300. However, as movement of the cradle 302 travels past the position 2300 such that the first cam catch 2102 travels past the outer follower point 2304, the cam 1104, and thus the cradle 302, will snap into position 2600. For example, consider a user releasing the cradle 302 when the first cam catch 2102 passes the outer follower point 2604. In such a case, the sloped profile of the outer follower surface 1604 is such that pressure from the outer follower surface 1604 (provided by the hinge spring 1110) against the first cam catch 2102 drives the cam 1104, and thus the carriage 302, into position 2600 independently of an externally applied (e.g., user applied) force.

For example, hinge 1100 is configured such that hinge 1100 will not disengage position 2600 unless a specified threshold force is applied to brace 302.

Further illustrated is that the engagement of the second cam catch 2308 with the cam stop 2310 causes the support plate 1108 to rotate with the cam 1104 when moving from position 2300 to position 2600. Generally, movement of the support plate 1108 enables the hinge 1100 to provide stability to the stand 302 when opened to various open positions.

Fig. 27 illustrates the stent 302 in the above-introduced position 2600. Further illustrated is a partial side cross-sectional view 2700 of the computing device 102, the computing device 102 including the bracket 302 attached to the cam 1104 of the hinge 1100 in a third open position. The cutaway view 2700, for example, corresponds to the cross-section 1700 illustrated in fig. 17.

As illustrated herein, in position 2600, the support plate 1108 partially protrudes from the hinge frame 1102. The movement of the support plate 1108 to the position 2600 is based on, for example, an interaction between the plate rail 1204 of the hinge bracket 1102 and the support channel 1306 of the support plate 1108. Further, the plate catch 2702 of the support plate 1108 engages the follower contact 2704 of the cam follower 1106. According to implementations, engagement of the plate catch 2702 with the follower contact 2704 prevents the support plate 1108 from rotating toward the further open position unless sufficient force is applied to the bracket 302.

For example, the engagement of plate catch 2702 with follower contact 2704 allows bracket 302 to be permanently retained in position 2600. Spring pressure from the hinge spring 1110, for example, holds the outer follower surface 1604 against the first cam catch 2102 and thereby prevents the cam 1104, and thus the bracket 302, from disengaging the position 2600 unless sufficient external force is applied. Thus, the plate catch 2702 will not disengage the follower contact 2704 in the absence of a force applied directly and/or indirectly to the bracket 302. For example, hinge 1100 is configured such that hinge 1100 will not disengage position 2600 unless a specified threshold force is applied to brace 302.

Under normal operating conditions, position 2600 is considered, for example, to be the maximum open position of cradle 302. As explained further below, movement of hinge 1100 through position 2600 is possible, but is considered an emergency exit option that prevents damage to cradle 302 when additional force is applied to the cradle.

Fig. 28 illustrates a partial rear view 2800 of the computing device 102 with the stand 302 in position 2600. The rear view 2800 illustrates that in the position 2600, the support plates 1108a, 1108b partially protrude from the hinge frame 1102. Further shown is the engagement between the second cam catch 2308 of the cam 1104 and the cam stop 2310 of the support plate 1108a, which allows the support plate 1108 to be moved between open positions.

Fig. 29 illustrates the stand 302 in position 2900. The position 2900 represents, for example, that the cradle 302 has rotated 180 degrees from the fully-closed position (e.g., from the position 1800 discussed above). In at least some embodiments, the location 2900 corresponds to an emergency egress location provided to prevent damage to the cradle 302 and/or other components. For example, rotation of the stand 302 to a further open position past the position 2600 discussed above (e.g., the third preset open position) is not considered a normal operating state. However, such rotation may occur, such as unintentionally, in response to various events.

For example, consider that computing device 102 is being placed on a desk or other surface with a stand at position 2600. The user may accidentally place an object, such as a book, on the computing device 102, which exerts sufficient force on the mount 302 to cause the mount 302 to disengage from the position 2600 and rotate to the position 2900. As described in further detail below, the force required to rotate the mount 302 from position 2600 to position 2900 is significantly greater than the force required to transition between the other open positions discussed above.

Further illustrated in fig. 29 is a side view 2902 of the hinge 1100 in a position 2900, the hinge 1100 including a hinge frame 1102, a cam 1104, a cam follower 1106, and a support plate 1108. In position 2900, the cam 1104 disengages the cam follower 1106 and the support plate 1108 remains engaged with the cam follower 1106 to allow the hinge 1100 to function as an integration and interconnection mechanism even in emergency exit situations. As discussed further above, this enables the user to return the stand 302 to the working position (e.g., one of the preset open positions discussed above) with minimal effort. For example, a user may apply a force to the mount 302 in the direction 2904 to return the mount 302 to one or more of the positions discussed above.

When the hinge 1100 is in position 2900, the support plate 1108 presses against the cam follower 1108. For example, the plate point 2906 of the support plate 1108 engages the follower point 2908 of the cam follower 1106 and applies pressure to the cam follower 1106. According to implementations, compressing the cam follower 1106 prevents the cam follower 1106 from engaging the cam 1104 until the cradle 302 is reset to the normal operating position.

Fig. 30 illustrates a side view 3000 of the hinge 1100 in the above-introduced position 2900. Side view 3000 illustrates that in position 2900, the cam 1104 is engaged with the support plates 1108a, 1108b via the engagement of the cam channel 1404 with the cam rail 1302. In addition, the support plates 1108a, 1108b engage the hinge frame 1102 via the engagement of the support channel 1306 with the plate rail 1204. This engagement of the cam 1104 with the support plate 1108 and the support plate 1108 with the hinge frame 1102 allows the components of the hinge 1100 to remain interconnected in position 2900. Thus, even with the cam 1104 completely removed from the hinge bracket 1102, the bracket 302 remains connected to the computing device 102 and can be returned to normal operating positions, such as those discussed above.

Side view 3000 further illustrates the engagement of the second cam catch 2308 with the cam stop 2310, which, as discussed above, pulls the support plate 1108 out of the hinge frame 1102 to various open positions in response to user manipulation of the bracket 302.

Fig. 31 illustrates a bottom view 3100 of hinge 1100 in position 2900. View 3100 illustrates the engagement of the support plate 1108b with the hinge frame 1102 via the support channel 1306 with the plate rail 1204. The engagement of the second cam catch 2308 of the cam 1104 with the cam stop 2310 of the support plate 1108a is further illustrated.

Fig. 32 illustrates a partial view 3200 of the cam 1104 relative to the support plate 1108 a. View 3200, for example, represents the position of cam 1104 relative to support plate 1108a when hinge 1100 is in a closed position (e.g., position 1800 discussed above). Included in view 3200 are a first cam catch 2102, a second cam catch 2308, and a cam stop 2310.

Fig. 33 illustrates a partial view 3300 of the cam 1104 relative to the support plate 1108 a. View 3300, for example, represents the position of the cam 1104 relative to the support plate 1108a when the hinge 1100 is in an open position (e.g., position 2600 discussed above and/or other open positions). Further illustrated is the engagement between the second cam catch 2308 and the cam stop 2310 of the support plate 1108, which enables movement of the support plate 1108 in response to movement of the cam 1104.

In at least some implementations, the contact surface of the cam stop 2310 that engages the second cam catch 2308 is angled inward toward the second cam catch 2308, e.g., not normal to the surface of the support plate 1108. In addition, the opposing contact surfaces of second cam catch 2308 are angled to provide a flat contact surface between cam stop 2310 and second cam catch 2308. According to implementations, this inward angling of the cam stops 2310 causes the second cam catches 2308 to pull the support plates 1108 inward and thereby provide stability to the various interconnected components of the hinge 1100.

Having discussed some example stand and hinge locations and components, consider now an example responsiveness profile associated with movement between different locations.

Hinge response profile

Considering the different positions of the hinge 1100 and the mount 302 discussed above, the response profile experienced during movement of the mount 302 between the different positions is affected by various factors. For example, pressure from the hinge spring 1110 against the cam follower 1106, and thus the cam 1104, provides pressure on the components. Depending on where these components are located, the pressure either resists or encourages movement of the components of the hinge 1100.

In addition, the interaction between the different surfaces of the cam 1104 and the cam follower 1106 contribute to the responsiveness profile of the hinge 1100 and the stand 302. For example, as the stand 302 moves from the closed position 1800 to the first open position 2000, the responsiveness of the hinge 1100 is determined by the contact between the inner cam surface 1400 and the inner follower surface 1602. The responsiveness of the hinge 1100 is determined by the contact between the outer cam surfaces 1402a, 1402b and the outer follower surfaces 1604b, 1604a, respectively, as the stand moves past the first open position 2000 to positions 2300, 2600. Thereby, the transition between the guiding surfaces takes place in the first open position 2000.

According to various implementations, the opening of the hinge 1100 after the third open position 2600 is based on an interaction between the support plate 1108 and the cam follower 1106. For example, the torque required to move the hinge 1100 to the position 2900 (e.g., the emergency exit position) is based on the interaction between the support plate 1108 and the cam follower 1106.

In at least some embodiments, the responsiveness of the hinge 1100 can be characterized via a moment profile that indicates various forces occurring during movement of the stand 302 between positions. For example, the interaction between different cam surfaces and different cam follower surfaces provides a detent mechanism that results in a tactile response profile for movement of the bracket 302 between different preset positions. Consider, for example, the following example torque profile.

Fig. 34 illustrates a moment diagram 3400 including an opening moment curve 3402 and a closing moment curve 3404. Moment diagram 3400 further includes an angle axis 3406 and a moment axis 3408. The angle axis 3406 (e.g., x-axis) indicates an opening angle value of the stand 302 relative to an associated apparatus (e.g., computing device 102). The moment axis 3408 (e.g., y-axis) indicates different moment values of the moment map 3400. In this particular example, the moment values are indicated in newton-millimeters (N-mm). However, this is not intended to be construed as limiting, and the torque value may be measured in a variety of different units. Further, different forces may be measured to characterize the movement of the hinge 1100 and/or the bracket 302.

According to one or more implementations, the opening torque curve 3402 represents the torque transferred from the brace 302 to the cam 1104 as the brace is opened (e.g., by user manipulation) from the closed position to the open positions. The closing torque curve 3404 represents the torque transferred from the bracket 302 to the cam 1104 as the bracket is moved (e.g., by user manipulation) from the open positions to the closed position.

As described in further detail below, different moment curves are associated with certain "action points" or "action zones" that exhibit the overall responsiveness profile of the hinge mechanism discussed herein. The opening torque curve 3402 includes, for example, a first opening peak 3410, a first opening threshold 3412, a second opening peak 3414, a second opening threshold 3416, a third opening peak 3418, and a third opening threshold 3420. Closing moment curve 3404 includes, for example, a first closing peak 3422, a first closing threshold 3424, a second closing peak 3426, a second closing threshold 3428, a third closing peak 3430, and a third closing threshold 3432. Example attributes of these different points/regions are now discussed.

As an example implementation, consider the stent 302 in a closed position, such as at 0 degrees on the moment diagram 3400. The user manipulates the brace 302 from the closed position toward the open position. After the opening torque curve 3402, the torque resisting the opening of the stent 302 gradually increases until the opening torque curve 3402 reaches a first opening peak 3410 at an open position of about 23 degrees. After the first opening peak 3410, the moment value decreases rapidly until the opening moment curve 3402 intersects the angle axis 3406 at the first opening threshold 3412. In this particular example, the first opening threshold 3412 is represented as an open position of approximately 27 degrees.

According to one or more embodiments, if the stent 302 is released before reaching the third occlusion threshold 3432 (e.g., at less than 23 degrees open), the stent will snap back into occlusion, e.g., 0 degrees. Further, if the stent 302 is released after the first opening threshold 3412, the stent 302 will snap into a first preset open position, such as 48 degrees. Thus, the first opening threshold 3412 represents a threshold opening position of the scaffold 302 that when exceeded allows the scaffold 302 to snap to a first preset opening position. The first preset open position corresponds, for example, to position 2000 discussed above.

If the third occlusion threshold 3432 is not exceeded and the stent 302 is released, the stent will snap back into the occluded position. For example, if the user releases the stent at an opening angle that is less than the third closing threshold 3432, the moment of play on the cam 1104 is characterized by a closing moment curve 3404.

Consider now that the user further maneuvers the stand from the first open position (e.g., at 48 degrees) toward the further open position. Continuing from 48 degrees on the opening torque curve 2202, it can be seen that the torque value rapidly increases to a second opening peak. In at least some embodiments, this increase in torque represents a threshold torque required to move the stent from a first preset open position (e.g., position 2000) to a second preset open position (e.g., position 2300). For example, the second peak of opening 3414 represents the moment required to disengage the first cam catch 2102 from the first follower catch 2104, as explained above with reference to fig. 21 and 23. In this particular example, the threshold moment represented by the second opening peak 2214 is approximately 230N-mm.

If the user manipulates the mount 302 past the second opening peak 3414, it can be seen that the moment value of the opening moment curve 3402 rapidly decreases until the opening moment curve 3402 intersects the angle axis 3406 at the second opening threshold 3416. In this particular example, the second opening threshold 3416 represents an open position of approximately 65 degrees. In accordance with one or more embodiments, if the stent 302 is released before the second closure threshold 3428 is reached (e.g., between the first preset open position and the second closure threshold 3428), the stent will snap back to the first preset open position. If the stent 302 is released after the second opening threshold 3416, the stent 302 will snap into a first preset open position, such as 84 degrees. Thus, the second opening threshold 3416 represents a threshold opening position that, when exceeded, allows the cradle 302 to snap to the second preset opening position. In at least some embodiments, the second preset open position represents position 2300 discussed above.

Consider now that the user further maneuvers the stand from the second open position (e.g., at 84 degrees) toward the further open position. Continuing from 84 degrees on the opening torque curve 3402, it can be seen that the torque value rapidly increases to a third opening peak. In at least some embodiments, this increase in torque represents a threshold torque required to move the stent from the second preset open position (e.g., position 2300) to the third preset open position (e.g., position 2600). For example, the third peak of opening 3418 represents the moment required to disengage the first cam catch 2102 from the second follower catch 2306, as illustrated above with reference to fig. 23 and 26. In this particular example, the threshold moment represented by the third opening peak 3418 is approximately 300N-mm.

If the user manipulates brace 302 past third opening peak 3418, it can be seen that the moment value of opening moment curve 3402 is rapidly decreasing until opening moment curve 3402 intersects angle axis 3406 at third opening threshold 3420. In this particular example, the third opening threshold 3420 represents an open position of approximately 100 degrees. According to one or more implementations, if the stent 302 is released before the first occlusion threshold 3424 is reached (e.g., between the second preset open position and the first occlusion threshold 3424), the stent will snap back to the second preset open position. If the brace 302 is released after reaching the third opening threshold 3420, the brace 302 will snap to a third preset open position, such as at 118 degrees. Thus, the third opening threshold 3420 represents a threshold opening position that, when exceeded, allows the cradle 302 to snap to a third preset opening position. In at least some embodiments, the third preset open position represents position 2600 as discussed above.

Continuing through the third preset open position at 118 degrees, it can be seen that the torque value rapidly increases past the previous open torque value. In at least some embodiments, this indicates that the brace 302 is not intended to be opened past the third preset open position (e.g., 118 degrees) under normal operating scenarios. For example, opening the cradle to pass through the third preset open position is based on an emergency exit scenario, such as discussed above with reference to fig. 29-31.

When the bracket 302 is closed from the open position 2600 and/or other open positions, the moment acting on the cam 1104 is characterized by a closing moment curve 3404. In general, the closing moment curve 3404 is interpreted inversely to the opening moment curve 3402 because the directions of motion (e.g., closing versus opening) are reversed. In at least some embodiments, for example, a negative moment value on the closing moment curve 3404 represents a closing moment applied by a user, and a positive moment value on the closing moment curve 3404 represents a tendency of the stent to bite into a certain position (e.g., a certain open position or to be closed) in the absence of resistance and/or force applied from the user.

For example, consider a user manipulating the stand 302 from a third preset open position of 118 degrees toward a closed position. From the third preset open position, through the closing moment curve 3404, it can be seen that the torsional forces occurring when closing the stent 302 are less than those occurring when opening the stent 302. The difference between the opening and closing moments in the moment profiles is caused, at least in part, by the different profiles of the different surfaces of the cam 1104 and the cam follower 1106.

As referenced above, the closing moment curve 3404 includes a first closing peak 3422, the first closing peak 3422 representing a threshold torque force required to move the stent 302 from the third preset open position to the second open position. As the stent is closed past the first peak closure value 3422, the closing moment resistance decreases until the closing moment curve 3404 intersects the angular axis 3406 at a first closure threshold 3424. In this particular example, the first closure threshold 3424 represents an opening angle of approximately 95 degrees. According to one or more implementations, if the user releases the brace 302 between the third preset open position and before reaching the third open threshold 3420, the brace 302 will snap back to the third preset open position. However, if the user releases the stent 302 after reaching the first occlusion threshold 3424 (e.g., at or less than about 95 degrees), the stent 302 will snap into a second preset open position.

A second peak closure 3426 represents a threshold torque required to move the stent 302 from the second preset open position to the first preset open position (e.g., transition from position 2300 to position 2000). As the stent is closed past the second peak closure value 3426, the closing moment resistance decreases until the closing moment curve 3404 intersects the angular axis 3406 at a second closure threshold 3428. In this particular example, the second closure threshold 3428 represents an opening angle of approximately 61 degrees.

In at least some embodiments, if the user releases the cradle 302 between the second preset open position and before the second opening threshold 3416 is reached, the cradle 302 will snap back to the second preset open position. However, if the user releases the stent 302 after reaching or exceeding the second closure threshold 3428 (e.g., at or less than about 61 degrees), the stent 302 will snap to the first preset open position.

The third closing peak 3430 represents a threshold torque required to move the stent 302 from the first preset open position to the closed position (e.g., transition from position 2000 to position 1800). As the stent is closed past the second peak closure value 3430, the closing moment resistance decreases rapidly until the closing moment curve 3404 intersects the angular axis 3406 at a third closure threshold 3432. In this particular example, the third closure threshold 3432 represents an opening angle of approximately 24 degrees.

In at least some embodiments, if the user releases the cradle 302 between the second preset open position and before the first opening threshold 3412 is reached, the cradle 302 will snap back to the first preset open position. However, if the user releases the stent 302 after reaching or exceeding the third occlusion threshold 3432 (e.g., at or less than about 24 degrees), the stent 302 will snap into the occluded position (e.g., 0 degrees).

As shown in fig. 34, the separation (e.g., difference) between the opening threshold and the closing threshold is minimized. For example, the difference between first opening threshold 3412 and third closing threshold 3432 is minimized. Further, the difference between second opening threshold 3416 and second closing threshold 3428 is minimized. Further, the difference between the third opening threshold 3420 and the first closing threshold 3424 is minimized. This facilitates "snapping" of the stent as it is moved between different positions and reduces the likelihood that the stent will sink into an unintended position (e.g., outside one of the preset open positions).

As further shown by moment diagram 3400, the hinge mechanisms discussed herein are designed to minimize the moment required to maintain a "snap-in" response. In at least some embodiments, this minimum moment is approximately 20N-mm. Furthermore, the opening moment curve 3402 and the closing moment curve 3404 are, for example, trapezoidal in shape, rather than sinusoidal. This illustrates a crisp transition between different preset hinge positions.

Thus, according to implementations, the torque curve characterizes the torque values applied during movement of the support 302. For example, the opening torque curve 3402 represents the torque applied to open the rack 302 from the closed position 1800 through the various open positions. Additionally, a closing moment curve 3404 represents the moment applied when closing the poppet 302 from the various open positions to the closed position 1800.

It should be noted that in closing moment curve 3404, a negative moment represents a user actively applying a moment to close the stent, e.g., an external force is applied to stent 302. A positive moment on the closing moment curve 3404 indicates that the stent tends to close itself due to forces generated within the hinge 1100 (e.g., by the hinge spring 1110) that cause the hinge to "snap" between positions.

Fig. 35 illustrates a torque diagram 3500 representing different torque forces occurring when the cradle is opened to a position 2900 (e.g., the emergency exit position discussed above). The moment diagram includes an opening moment curve 3502, a closing moment curve 3504, an angle axis 3506, and a moment axis 3508. The preset open positions discussed above are further illustrated.

Moment diagram 3500 includes an emergency release peak 3510, which emergency release peak 3510 corresponds to the amount of moment required to disengage rack 302 from the third preset open position to a further open position (e.g., to open rack 302 to position 2900). As indicated above, in at least some implementations, the stand 302 is not intended to be opened past the third preset open position under normal operating conditions. Thus, the amount of torque required to open further past the third preset open position is much greater than the torque values discussed in relation to the previous open position.

In this particular example, the emergency release peak 3510 indicates that approximately 1700N-mm is required to open the scaffold 302 past the third threshold open position. For example, the emergency release peak 3510 specifies the amount of opening torque on the bracket 302 required to disengage the plate catch 2702 from the follower catch 2704, as discussed above with reference to fig. 27. Thus, exceeding the opening torque specified by the emergency release peak 3510 when the cradle 302 is in the third preset open position causes the cradle to transition to the emergency off-board position (e.g., position 2900).

Note that in the moment diagram 3500, the closing moment curve 3504 is different from the closing moment curve 3404 discussed above with reference to fig. 34. The closing moment curve 3504 demonstrates that there is little resistance to returning the hinge 110 to the normal operating state when the cradle 302 is opened past the third preset open position to the emergency off-board position.

For example, refer back to fig. 29. As illustrated in fig. 29, the support plate 1108 holds the cam follower 1106 in a compressed position within the hinge frame 1102 when the hinge 1100 is opened to a position 2900. When the bracket 302 is closed from the position 2900, the cam follower 1106 does not engage the cam 1104 as the cam follower 1106 is compressed until the bracket 302 pushes the support plate 1108 to disengage the support plate 1108 from the cam follower 1106. When the support plate 1108 disengages the cam follower 1106, the hinge spring 1110 presses the cam follower 1106 into engagement with the cam 1104, thereby restoring the hinge 1100 to a normal operating state. In at least some implementations, the hinge resetting occurs at an open position of 48 degrees (e.g., a first preset open position and/or position 2000).

Accordingly, the embodiments discussed herein provide a stable hinge mechanism that allows an attached component (e.g., a bracket) to be adjusted between a plurality of preset positions. It will be appreciated that the example device orientations, stand positions, hinge preset positions, moment values, etc., discussed above are presented for purposes of example only. Accordingly, a wide variety of different device orientations, stand positions, hinge preset positions, and moment values not specifically mentioned herein may be implemented within the spirit and scope of the claimed embodiments.

For example, an attachment mechanism (e.g., hinge 1100 discussed above) used to attach the stand to the computing device may include any number and/or configuration of suitable preset detent positions to enable the stand to be opened to a variety of different positions to support various orientations of the computing device. Further, according to the claimed embodiments, the example hinge may be attached to any suitable location and/or portion of the stand and/or computing device.

The computer-readable medium 3606 may be configured in various ways as further described below.

Input/output interface 3608 represents functionality that allows a user to enter commands and information to computing device 3602, and that also allows information to be presented to the user and/or other components or devices using various input/output devices.

Various techniques may be described herein in the general context of software, hardware elements, or program modules. Generally, such modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types.

Computer readable media can include a variety of media that can be accessed by computing device 3602. By way of example, and not limitation, computer-readable media may comprise "computer-readable storage media" and "computer-readable signal media".

"computer-readable storage medium" may refer to media and/or devices that enable persistent storage of information relative to mere signal transmission, carrier waves, or signals per se. Accordingly, computer-readable storage media refers to non-signal bearing media. Computer-readable storage media includes hardware such as volatile and nonvolatile, removable and non-removable media and/or storage devices implemented in a method or technology suitable for storage of information such as computer-readable instructions, data structures, program modules, logic elements/circuits, or other data.

A "computer-readable signal medium" may refer to a signal-bearing medium configured to transmit the instructions to hardware of computing device 3602, such as via a network. Signal media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave, data signal, or other transport mechanism. Signal media also include any information delivery media. The term "modulated data signal" means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

As described previously, the hardware elements 3610 and the computer-readable medium 3606 represent modules, programmable device logic, and/or fixed device logic implemented in hardware that may be employed by certain embodiments to implement at least some aspects of the techniques described herein, such as executing one or more instructions. The hardware may include integrated circuits or systems-on-chips, Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), Complex Programmable Logic Devices (CPLDs), and components implemented in silicon or other hardware.

Combinations of the foregoing may also be employed to implement the various techniques described herein. Thus, software, hardware, or executable modules may be implemented as one or more instructions and/or logic implemented on some form of computer-readable storage medium and/or by one or more hardware elements 3610. The computing device 3602 may be configured to implement particular instructions and/or functions corresponding to software and/or hardware modules. Thus, implementations of modules executable as software by the computing device 3602 may be accomplished, at least in part, in hardware, for example, through the use of computer-readable storage media and/or hardware elements 3610 of the processing system 3604. The instructions and/or functions may be executable/operable by one or more articles of manufacture (e.g., one or more computing devices 3602 and/or processing systems 3604) to implement the techniques, modules, and examples described herein.
